Spring 应用程序不能在 JBOSS 中运行，但可以与 Tomcat 一起使用

Question

这就是我正在做的事情。

在 jboss 中部署此应用程序失败，因为它在 tomcat 中部署并像魅力一样工作。

我正在使用来自 Eclipse 的动态 Web 应用程序作为项目源。

将项目导出到war文件并部署在jboss服务器中也行不通。

控制器：

import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class AnotherTest {

    static Logger logger = Logger.getLogger(AnotherTest.class);
    @RequestMapping(produces=MediaType.APPLICATION_JSON_VALUE,value="/ahi")
    @ResponseBody

    public String test(String[] args) {
        logger.debug("logging");
        System.out.println("Hello"); 
        String message = "{\"a\":\"b\"}";
        return message;
    }

}   

JBOSS 中的错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/exc/InvalidDefinitionException

Answer 1

添加maven版本jackson如下图

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.4</version>
</dependency>
